CURRENT-COLLECTOR- Patented July 31, 1906.

To all whom it may concern: 1

Be it known that we, ARTHUR LINDEN, a

subjectof the King of Sweden, and PAUL HIERSEMANN, a subject of the King of Saxony,

and residents of Vesteras, Sweden, have in railways where the height of the contact-wire over the ground varies considerably.

The invention consists, chiefly, in that the contact-bow is pivotally connected to the vertically-guided upper point of a rhombguide the lower rods of which are turnable on axles located at some distance from each other and mechanically connected to each other, so that their turning in one and the same direction, and thereby the tilting of the guide in the one direction or the other, is prevented.

In the accompanying drawings we have illustrated a contact device embodying our invention.

Figure 1 is aside view of the supply-conductor, and Fig. 2 a frontelevation of the same.

The dotted lines 1 indicate the part of a car on which the contact device is provided. On the roof of the car are journaled an insulated axle 2, extending across the roof, and two shorter axles 3 on each side of the lantern of the car. To the said axles 2 and 3 are pivotallyconnected rods 5, to the upper ends of which are hinged frames 6 and 7, pivotally connected to each other at their upper ends, so that the said frames, together with the rods 5, constitute a rhomb-guide, the top or point of which is-movable vertically or approximately vertically. At the said point the contact-bow proper, 8, is journaled, the I same being provided with downward-projecting parts 9, actuated by springs 10 and 1 1-, which are secured to links and 16 and tend to keep the contact-bowin a vertical position. The said links 15 and 16 are hinged to the frames 6 and 7 and to each other.

On account of the friction against the contaot wire 12 the contact -bow durin the movement of the car will automatical y be turned backward in relation to the direction of movement. (Indicated by the arrow'in Fig. 1.) If the direction of movement of the car be changed,'the contact-bow will be antomatically turned over in'the opposite di-- rection to that shown in the drawings, such turning over being accomplished without difliculty on account of the small height of the contact-bow, which requires only a slight lifting of the contact-wire for allowing the contact-bow to turn over.

The rods 5 or their axles are actuated springs 13, tending to turnthe said rods toward each other, so as to press with desired force the contact-bow upward. In order to prevent the rods 5 from being turned in one and the same direction, whereby the rhombguide would be tilted, the said rods or their axles are mechanically connected to each otherfor instance, by means of a chain 14 and chain-wheels or toothed segments or the likecompelling the said rods to turn in opposite directions.

Having now particularly described our invention, what we claim as new, and desire to I secure by Letters Patent, is-

1. In an overhead supply-conductor for electric' railways the combination, of a. con- 1, tact-bow, a rhomb-guide to the top of which the said contact -bow is connected, links hinged to the said rhomb-guide and to each other, springs between the said links and the said contact-bow and mechanical connec-. tions between the lower rods of the said rhomb-guide, substantially as and for the purpose set forth.

2. In anoverhead supply-conductor for electric railways the combination of axles disposed at some distance from each other, a

rhomb-guide the lower rods of which are con nected to the said axles, mechanical connecnames to this specification in the presence of tions blftween the (siaid axles, a OO?t&Ct -b0\5 two subscribing Witnesses. pivota y connecte t0 the top 0 the sai 1 rhomb-guide, links hinged to the latter and S to each other, and springs between the said links and the said contact-bow substantially as and for the purpose set forth.

In testimony whereof We have signed our Witnesses CARL WYKBORNJ, THURO PAULsEN.
